Six men were arrested yesterday by detectives investigating the killing of a man stabbed to death on 21 May as he delivered a curry outside the Solicitor General's home in north London.

The arrests came after searches of two properties in east London and Birmingham. All the arrests were made in east London. Abdul Samad, 25, died from stab wounds after apparently being lured to a street in Islington, north London, by a bogus curry order from a public telephone box. The six men, aged between 25 and 40, were arrested on suspicion of murder and were being questioned at two north London police stations.
